[sdiy] Drilling 'square' holes

[Jim Patchell]

    The best way is to use an end mill.  Fiber glass is soft enough that you
should be able to do this in a drill press.  You will need to get an X-Y
table.  Also, buy a lot of milling bits.  Fiber glass is even worse that
milling steel.  PCB houses basically do the same thing.  Except they use an NC
router.
